Abstract (en)

[origin: WO9916225A1] A method for processing Executable Objects, comprising: (a) providing analysis means capable of non-interfering analysis of data packets transmitted on a communication line between a browser and an HTTP server on the web, said communication line being established through a gateway; (b) analyzing the handshake between said browser and said server, to detect a "GET_" command sent by the user and an HTTP code sent in response by said server; (c) when such an HTTP code is detected, analyzing the data packets transmitted by said server to said browser, by: (c.1) providing ordering means to order data packets received in non-sequential order, and to forward them in sequential order to header checking means; (c.2) checking the data packets so as to analyze the contents of the header of the Executable Object, and to identify the resources of the system that it needs to employ; (c.3) transmitting to said gateway data representing the resources of the system that the Executable Object needs to utilize; (c.4) providing data packet suppressing means coupled to said gateway, such that if the resources of the system that the Executable Object needs to utilize are not permitted according to the security policy set by the administrator, at least one data packet belonging to the Executable Object is suppressed, altered or damaged, so as to prevent the execution thereof by the browser.
